"Revolutionary Breakthrough: Scientists Successfully Grow Human Embryo from Scratch"

Scientists at the Weizmann Institute have successfully grown an embryo model using stem cells, resembling a 14-day-old human embryo. The model, created without the use of sperm, eggs, or a womb, closely mimics the structures and development of a real embryo. This breakthrough could provide an ethical way to study the early stages of human life, which are poorly understood and a major source of miscarriage and birth defects. The embryo models could help researchers understand organ development, genetic diseases, and improve in vitro fertilization success rates. However, the current 99% failure rate needs improvement, and the ethical implications of mimicking embryo development beyond the 14-day stage are being debated.
